The Smart SRS ships with powerful external speakers which provide excellent quality audio in meeting rooms. We found however that the speakers were slightly overpowering in smaller meeting rooms so modified the configuration of one of our SRS-M’s to use the built in sound bar. Quality is still very good with the added bonus of a much more streamlined look to the screen. We wouldn’t recommend this in larger, noisy meeting rooms but in the smaller room it is a nice neat solution.
